Flight coming out of Buffalo was delayed, so we had to be rescheduled on another flight from Baltimore to Phoenix which means we had a long layover and got home 3.5 hours late. Shuttle to parking stopped at 10pm, so we had to pay for an Uber to the parking lot and got charged an extra day of parking since it was after midnight. Not the best experience. Long day!

Was fine, delayed and feels like southwest is always late

I don't know why flying out of Sarasota requires two plane changes.

The first time I flew in the extra legroom section. It was difficult to notice a difference. I had bad luck with my neighbors. The crew was okay. Southwest has reduced the live TV options.

The flight was smooth. The Southwest experience has degraded overall, but this one was okay.

No gluten free snacks. Seats felt worn or bare bones even though it was a new 737 MAX 8.

One major problem that was very unprofessional and uncalled for. Plane landed and we had to wait 20 minutes to get off the plane since they were waiting for someone to come to the gate to drive the jetway. Southwest couldn't have someone available and waiting for the plane to land? Is there only one person in Hobby airport who knows to drive the jetway? Was he at lunch? In the bar? Uncomfortable and uncalled for!

The checking experience in Orlando was terrible, almost missed the flight. Too many travelers and Southwest completely understaffed.

I'm glad it wasn't only 75% full because I could get a good seat

if I was good. Not happy that I have to pay extra money to get the seat I need for lake room, but I guess that’s a sign of the times.

I’m biased. I work at the airport and within these systems so I know how to be effective. On top of that part though everyone was friendly and helpful. Both legs of my trip were on time. My baggage was handled with care. Alaska’s part of my experience was top notch.

The TSA pre check with photo linked to Alaskan airlines was extremely fast & convenient.

My suggestion is that they should provide USB-C charging ports for modern cell phones.

With saver fares on Alaska, you are treated like a 2nd class citizen. Last to get a seat-most likely in the middle. Last to board. By then all overhead bins are taken. It’s sad to see Alaska treats its customer like India’s caste hierarchy. I’m in Portland Oregon. So I have to Alaska. Otherwise, I wouldn’t fly on them again.

I paid for the $8 WiFi for the flight and it never worked. The crew told me it goes in and out and to keep trying. I didn’t get to watch the show I had planned to watch, bummer that I paid for the service. The person next to me said she has never been successful with in flight WiFi.

The flight was delayed by 2 hours for “routine maintenance”and because of that I arrived much later iso my Uber ride home was $100 when it’s normally $50.

The airport crew and on board experience was fine. The problem with Alaska air is that there is zero customer service over the phone when you’re trying to buy your ticket or change anything.

More or less, this seemed like a mismanaged group of great people who would crush at this job, if only they were given the resources to do so.

I enjoyed the feet space in comparison to other airlines. The snacks were also better, great service and the pilot greeted and said hi which made me feel safer.

Well the seats were very tight but the plane was very clean, the attendance great and good entertainment. Maybe they had it, but I wanted a map on the app. Thanks

I had to run from the end of terminal one to the end of terminal two to make the connecting flight....probably a kilometer. No electric carts were available. I'm 76 and literally had to run to make the connection at the last minute. The connecting time was absolutely unrealistic. When Last Call was announced, I tried to get other Copa gate staff to call Gate 221 to let them know I was on my way, but they said no. I came within 1 minute of missing the flight.

Boarding was a mess, they call all priority members without distinction so gold, platinum, silver were all mixed together in a long line which defeats the purpose

Do not book it’s a scam! They stole $1200 from me

There should be a warning regarding the quality of the aircraft on the website as we reserve the tickets. There was no TV or any type of screen onboard. The wifi they offer is good for nothing. Traveling 9 hours straight with kids and no type of entetainment was horrible. I wish I had been informed prior so I could buy a ticket with another airline. The food was a joke too. A very tiny portion per passenger. They also charged $100 per checked bag. With United I used to pay $60. So, fair to say that I wont be flying Copa anymore. Their aircraft was super old, outdated, no entertainment, with nearly no onboard food.

The flight was good overall. Everything went smoothly, although the landing was a bit rough. Still, it was a pleasant experience

Very strict carry on rules meant most of the plane had to gate check their luggage. As is often the case had things that were broken because of this, but I appreciated not being charged to gate check. Otherwise good flight and great crew once on the plane

I liked the meatloaf the chicken was awful but the plane was on time and got there and the staff was nice.

Boarding was quick & efficient; they gave boarding groups due priority; staff & air crew were very cordial and helpful, pleasant flight.

Very happy with my flight. I would definitely recommend it.

Did upgrade, travel in business it was great (more room I could sleep)

Even through the flight was delayed due to storms near IAH The flight was great! The crew was so hospitable and professional

I flew from Santa Fe to Denver to catch a flight to London and the transfer of my luggage on arrival at Denver to the London flight worked perfectly. The crew on the ground and on board for the London flight were so friendly and efficient.

Boarded early; and arrived home 40 mins early. After a long flight, it’s nice to be back home early. These flights have no amenities; no snacks. So need to bring your own

Boarded early, left early, arrived 40 mins early! A win win for me!

New plane was lovely. Crew customer service is always lax but expected. Kraft on time and arrived safely.

These airplanes should be illegal. The seats are two tight, it is a safety issue. Wheelchair support was ridiculously slow. We almost missed our flight.

It was a short flight so I was expecting too much

Horrifying Almost 2 million miles. Bring your own food and drink. One coffee or drink every three hours. Have to order meals on app more than 24 hours ahead Tiny and dirty bathrooms

Flight was delayed but more than 90 minutes. This caused me to miss my available windows for pick-up by a friend. I had to pay $125 for an uber back home from the airport which was an added expense that I had not budgeted for my trip. Staff was friendly.

I felt scammed. The priced advertised was different than what I paid. I paid the whole some online. I then got a call 20 minutes later saying I need to paid 70 more person. She said the price online is not the guaranteed price.

Our flight was repeatedly delayed for maintenance problems: scheduled for 9.30am, eventually delayed to 7pm! Very very inconvenient! AA should have provided a substitute plane much earlier.. On the other hand, Customer Service crew in Charlotte helped us to reach NY (LGA) by late afternoon. Thank you Patricia!! The actual flight was quick and very comfortable. As always a. excellent, professional crew. [no food on a a short hop).

Take-off delayed an hour because of a missing flight officer, so,arrived in Charlotte lates causing many passengers to miss connections. Otherwise a very good flight, safe and comfortable, with an excellent professional crew.

Little time between flight from Dallas to flight to Gainesville. We chose this one, 43 minutes between, because the price for a connection with at least an hour between, was so much higher. Had to ask passengers on the Dallas flight to please allow us to deplane ahead of them. The economy passengers allowed this. We had to walk very fast to the next gate, 35 gates away. Thankfully all in the same terminal. Getting to the small Gainesville plane was a little confusing as you enter an area that is boarding many small planes at the same time. We stood in the wrong line for about 15 seconds before realizing it was not our Gainesville flight. Since I had boarded at this gate in the past, I knew to check the signs carefully so we weren’t lost. The first class seat experience was wonderful. I really enjoyed the upgrade. We were offered an alcohol drink as soon as we sat down. I got something different but it was a great gesture especially since we really had to hurry to make the flight. We had packed expecting we might miss this connection, but made it. Our luggage didn’t miss the flight. American Airlines delivered our bags to our home the next day. That was very convenient!

The plane was large, not full, but one with 3 seats near each window and 4 in a row in the middle of the plane. There were screens on the backs of the seats for entertainment and information. To use the entertainment one needs ear plugs that physically plug into the screen. My husband had some he let me use as I only had blue tooth type. The stewards gave out some headphones to some, but when my neighbor asked for some, the steward said no. So maybe they ran out? Idk. Bring the old kind of headphones or earbuds if you want entertainment in case this is the type of entertainment offered. We had a very tight connection in Miami. 43 minutes. The other economy passengers allowed us to get ahead of them because I asked if we could since we were near boarding time for our next flight and 35 gates away. They were extremely kind. First class wasn’t going to allow us to pass through. We did make the next flight. Our baggage didn’t, but they were delivered to us the next day and we were prepared with essentials in our carry on packs.

Food is what you expect on a plane. Nothing gluten free. But that is expected. Drinks, apple juice, was fine. Seat, what I expected. Fine.

The check in agents in PHL and gate agents had to have been the rudest women that I have ever encountered; the agent weighing the bags at check in screamed continuously at all of the guests as did the woman at the gate.I have Executive Platinum status with AA and fly a lot with AA but these ladies were the absolute worst I had the displeasure to encounter!

Everything went as planned. The only issue I had was with the gate C31 attendant. The person could barely speak English and was very difficult to understand.

The flight took off an hour late which made the connection concerning

My pillow had a shoe print on it, when I asked if I can have another pillow, I was told “I’m sorry but it is one pillow per guest, do YOU want to turn it inside out” to which I responded , no thanks I will go without. This is generally not ok, but For the price tag I paid flying business this is absolutely unacceptable. Hopefully American Airlines can update their accommodations to bedding that is not tossed on the ground and stepped on, or at least have a couple of extra pillows in hand, incase someone had decided to step on the pillows for what ever reason

The flight from LA to Chicago was smooth and service was very good overall.
